New method to predict in advance settlement of ground under multi-stage filling

A new method named settlement differential method was proposed.By use of the method the settlement of ground could be predicted in advance under the condition that fill material was added onto the ground by layer.The development of ground settlement at different filling stages was revealed,so the ground settlement data observed at different filling stages could be used in linear fitting to predict the ultimate ground settlement.It was useful in fill construction that the ultimate settlement of ground could be precisely predicted in the course of filling.
